This top-rated scientific calculator app out-thinks many dedicated calculator devices. It includes fraction and algebraic calculations; binary, octal, and hexadecimal number systems; trig functions; percentages; and much more.

In terms of non-calculator features, there are 10 memory slots, landscape mode, user-customizable conversions, and a built-in help feature. This update fixes many bugs and offers several new options like using the device’s auto rotate setting, as well as other improvements.

This spooky time makes some ponder fate and the signs of the Zodiac. Whether you believe or not, it might surprise you to know that horoscopes remain some of the most popular sections of magazines, newspapers, and now Android.

For a digital daily horoscope delivered to your ‘droid, try this fresh app. You’ll get, daily updates, a horoscope for the whole year, a description of your sign’s characteristics, and the ability to share your horoscopes over social networks.

Perhaps the best feature for believers – the Love Affinity section that shows your compatible signs.

Get yourself and your Android into the spirit of tonight’s festivities by downloading this special themed game.

You’ll find two modes – Puzzle and Arcade. The Puzzle mode includes over 3500 levels, many of which are exclusive to this Halloween edition. Just like regular Bubble Blast games you must strategically burst – in this case, pumpkins – to set off a chain reaction of destruction and clear the board. You have a limited number of bursts per level.

This edition’s themes include jack-o-lanterns, ghosts, devils and other scary characters and you’ll hear a frightening cry when you succeed, and a witch’s laugh when you lose.
